Ultrasonic oxygen sensor Gasboard 8500D

Gasboard 8500D ultrasonic oxygen sensor is an economical gas sensor used to detect oxygen concentration in binary gases. By adopting ultrasonic detecting technology, it is very stable and there is no need to calibrate the sensor in the application. It is mainly designed for ventilator oxygen concentration measurement with high flow range up to 80L and for the large PSA generator too.Compared with electro-chemical oxygen sensors, it has a much longer lifespan and a more stable performance. Features ▪ Cutting-edge ultrasonic technology adopted ▪ High accuracy, high stability, low cost, small size ▪ Full scale temperature compensation ▪ Factory calibration, maintenance free ▪ Long lifespan ▪ High flow range supportive Applications ▪ Medical ventilator ▪ Respiratory devices ▪ Anesthetic machine ▪ Large PSA oxygen generator SPECIFICATIONS Measurement range O2:(withstand flow range: 0~80L) Resolution 0.1% Concentration accuracy ±1.8%FS @(10-45)℃ Response time 5s Working temperature 10℃~50℃ Storage temperature -20℃~60℃ Working humidity 5~85%RH(non-condensing) Max pressure 150Kpa Power supply DC 5~12 Signal output UART-TTL Dimension W60*H30*D26(mm)
